APPENDIX,- 
'wer© getting to the base of the mountain, they were only ha a. 
few instances without abundance of buffaloe meat. 
Three days took them over to the plams of Mad river, (the 
name given the Big Horn above this mountain) which following 
for a number of days, they left it where it w T as reduced to 80 yards 
in width, and the same evening reached the banks of the Colo¬ 
rado or Spanish river. Finding flocks of buffaloe at the end o£ 
the third day’s travel on this stream, the party passed a week 
in drying buffaloe meat for the residue of the voyage, as in all 
probability those were the last animals of the kind they would 
meet with. From this camp, in one day, they crossed the di¬ 
viding mountain, and pitched their tents on Floback’s fork of 
Mad river, where it was near 150 feet broad, and in eight days 
more having passed several stupendous ridges, they encamped 
in the vicinity of the establishment made by Mr. Henry, in the 
fall of 1810, on a fork about 70 yards wide, bearing the name 
of that gentleman; having travelled from the main Missouri 
&bout 900 miles in 54 days. 
Here abandoning their horses, the party constructed canoes 
and descended the Snake or Ky-eye-nem river, (made by the 
junction of Mad river, south of Henry’s fork) 40u miles, in the 
course of which they were obliged by the intervention of im¬ 
passable rapids to make a number of portages, till at length they 
found the river confined between gloomy precipices at least 200 
feet perpendicular, whose banks for the most part were washed 
by this turbulent stream, which for 30 miles was a continual 
succession of falls, cascades and rapids. Mr. Cook’s canoe had 
split and upset in the middle of a rapid, by which one man was 
drowned, named Antonie Clappin, and that gentleman saved 
himself only by extreme exertion in swimming. From the re¬ 
peated losses by the upsetting of canoes, our stock of provisions 
Were now reduced to a bare sufficiency for five days, totally ig¬ 
norant of the country where they were, and unsuccessful in 
meeting any of the natives from whom they could hope for in¬ 
formation. 
Unable to proceed by water, Messrs. McKenzie, McClelland 
and Reed, set out in different directions, inclining down the idv r 
er, for the purpose of finding Indians and buying horses. JVIiv
